SEALED CONTAINER. I

Application filed May 29, 1925. Serial No. 33,650.

The object of my invention is to provide a container. such as an ordinary tin can, with a metal ,Fealat one end which will be securely attached thereto to pretentthe entrance of air and moisture and trill serve cover laterally and tuck it partially under 1 said curled edge portion of the body, caus- .ing the material of said marginal portion to flow as required to be pressed under said curled. edge and make a. tight fit therewith, a portion of he margin resting upon said curled edge portion.

My invention also comprises novel details of improvement that will be more fully,

hereinafter set forth and then pointed out in the claims;

Reference is to be had to the accompanying drawings forming a pairthereof,

wherein-- Fig. 1 is a partly sectional side view of a container upon which the sealing cover is applied ready to, be secured to the container;

Fig. 2 is a sectional view illustrating the sealing cover secured on the container; and

Figs. 3 and 4: are sectional views illustrating steps in the method of securing the container and its sealing cover together.

Similar numerals of reference indicate corresponding parts in the several views.

The container body 1 may be of. any well known construction. such as customary in making so-calicd tin cans or sheet metal containers, provided with bottom 2 which maybe secured to the body by means of suitable seaming tools or by solder or in any well known way. At the open end of the body, opposite the bottom 2 the metal at the edge is extended or curled inwardly forming a head or rib atfl servingto stillen the mouihot the body and to ooperate with a scaling cover e. The scaling cover 4 may be inadcot suitable thin metal and is provided with a curved nuirginal portion 5 that isadaptcd to ht against the curled edge 3 of body 1, as illustrated in,

.tight sealing of the parts.

sealing cover before the latter is applied upon the body 1 to'assist in producinga The margmal port on?) of the sealing cover 18 placed upthe inner part of said portion 5 is forced laterally and partly underthe curled edge 3 of the body, the manor the seal flowing in such a manner as to force or tuck the metal tightly into engagement with the curled edge 3, throughout the extent of the portion 5, the outer part oredge of the marginal portionsbeingdrawn inwardly along the curled edge of body 1 and restingthere- The sealed container is indicated in the open end of the body. V

Suitable means may be provided for pressmg the marginal p'ortionfi of the sealing cover uncler and into'engagement with the curled edge 3 of-body 1. In Figs. 3 and 4 I have illustrated rollers 6 having suitable annularly curved end portions 6*. adapted to engage the-metal-of the sealing cover to force its marginal portion?) intoengagement with the curled edge? of body 1:, Therollers 6 are pivotally supported upon rock arms 7, shown in bell-crank'form, that-are pivotally supported upon a head 9"which may be supported in :any suitable manner. At 10 is a rodior plunger slidably guided in a bore 11 of head 9 and'preterably kept from rotating by a key 12. ,The rod or plunger 10 is operati'yely connected with the arms .7 by, means of a pin L-l carried by the rod 95 or plunger and operative in slots ,75 in said arms, whereby when the plunger is pushed toward body 1- the arms 7 will, be-til tedto force the rollers-6 latirally for expanding the metal-oi" marginal portion 5 of the seal- :00

ing cover 4, and when the operation-of the rod IS IGYGTSBd the roll'ers'will be. withdrawn of applying the sealing. cover to'the container body the; parts will be assembled sub-v 105.

stantially "as indicated in Fig. 3-; rod or plunger 10 will be rotated and be pushed toward the body "lz During such rotation. of rod or plunger-10'the rollers 6 will be. forced laterally. with theiredgesgtii brought 119 In "the operationx into contact with the metal at the point where the cover and marginal portion 5 join,

whereby the metal of'such portion will be,

In accordance with my invention I am enabled to make a tight fit between the curled edge3 of body 1 and the marginal portion 5 of the sealing cover, whereby the latter is retained from being pushed in or from being forced out from the body.

Such sealing'cover may be applied after the body has been char ed with the desired contents. When it is'dbsired to remove the sealmg cover it is merely necessary to pry the same up by inserting therethrough a suit-.

able tool, such as an ice pick or strong nail, whereby the seal Will snap from the body without disturbing or hurting the latter in any way. Y

The body may be provided with a removable cover 14: particularly for use after the sealing cover has been removed, and to protect the sealing cover during transportation. In the example illustrated the cover let has a flange 15 provided with threads 16 adapted to coo erate with threads 17 on the container b0 y, said threads" being so'related that they will cause the cover to be retained with a tight fit on the body. I The outer edge of the sealing cover is located sufficiently close to the rim of the body 1 not to interfere with flange 15. The'cover 14 may be applied bywrotating it in one direction and may ;be.'remoted by rotating it neversely.

' Aniridenture or depression 18 in cover 14 is adapted to fit within the inner surface of the curled edge 3 of the containerbody when the sealing cover has been removed, and such indenture will fit within the inner marginal parition of seal '4. A' slip cover-orany other form of detachable cover for the can bod may beused if preferred.

l\ y improvement permits the sealing ofcan bodies in such a way as to prevent sur reptitious access to the contents; Wlll preserve the contents from air and moisture,

and helps stiffen the charged container.

Having now described my invention what 1 claim is 1. A container having an open end and provided with a, sealing cover at said end, said end of the container havin an nrivaardly extending edge portion an the sealingcover having a marginal portion extending under said edge portion in engagement therewith and having the outer edge of the marginal portionrestmg upon and terminatmg at the edge portion of the container in a-vposition to permit the sealing cover to be pried from the body bya tool forced through said cover and pressed against the adjacent edge of the sealing cover;

2. A container having an open end-and provided with a sealing cover at .said end, said end of the container havin an inwardly extending edge portion an? the sealing cover having a marginal portion extending under said edge portion'fin' engagement therewith and having the outer edge of the marginal portion restingupon and terminatmg at the edge portion of the container- 11116. a removable cover to-fit over andagainst the marginal portion of the sealing cever and to fit against the open end .of thebody'when" the sealing cover is absentfrom the-bod the removable cover-.havinig-a flange tov v t around the body unobstructed by thesealing cover, the body and said fiange'having cooperative means. to retain the removable cover upon the sealing cover and-.nponthe open end of the body whenthefsea-li rover is absent therefrom.
